This page is for existing boot9strap users to update their installation of boot9strap to the latest version.

Note that the recent major release of Luma3DS is not compatible with boot9strap version 1.0. It requires you to update your boot9strap installation to version 1.2 by following the instructions on this page.

There have been reports of a wave of bans being handed out to CFW users by Nintendo. To protect yourself, please do the following steps before starting this guide:

  1. Go to System Settings, then “Internet Settings”, then “SpotPass”, then “Sending of System Information”
  2. Disable the “Sending of System Information” option
  3. Exit the System Settings
  4. Go to your Friend’s List (the Face Icon in the top row of your Home Menu)
    • If you receive an error and are kicked out of the menu, the Friend’s List setting is already disabled
  5. Go to the Friend’s List settings, then “Friend Notification Settings”, then “Show friends what you’re playing”
  6. Disable the “Show friends what you’re playing” option
  7. Exit your Friend’s List
